A bra, a battery and a set of jump leads walk into a bar. The battery and the jump leads take a seat whilst the bra goes up to the bar.
The bra says to the barman "Afternoon pal, three pints of Stella please "Sorry mate" says the barman "I can't serve you". "Why not" the bra says. "Coz you're off your tits and your mates look like they're going to start something".
